Gaussian filter
For Gaussian, we need a range to select the Gaussian blur kernel; we will use another input range but we have to limit it to only selecting odd values. To do this, we set up the default value as 3 and a step of 2, with a range between 1 and 55:
<div id="step3_o2" class="step_blocks hide"> <span class="step">3</span> Kernel Filter size: <span id="value_o2_sel">3x3</span> <input type="range" class="custom-range" min="1" max="55" value="3" step="2" id="value_o2"> </div>
